It is part of an electric or hydraulic power steering system in which the frame is a steering gear housing for a ball-nut spindle or ball-nut hydrostatic transmission.
  • the servo motor is formed as an electric motor whose motor shaft is rotatably connected to a pulley and having a belt which runs on a non-rotatably fixed to the nut pulley.
  • the belt for connecting the two pulleys is preferably a toothed belt, but may also be a V-belt or V-ribbed belt.
  • To adjust the belt tension of the servo motor is designed to be radially displaceable and fixable relative to the longitudinal axis of the axially displaceable component and the nut.
  • Fig. 1 is a partial longitudinal section through a formed as a steering gear housing 17 frame 4 of an electric power steering 1 shown.
  • An electric servo motor 2 serves to provide a steering assist force on a formed as a spindle 15, in the steering housing 17 axially displaceably mounted component 3.
  • the spindle 15 is a ball screw, consisting of a ball screw 23 between the spindle 15 and a nut 5, the is arranged rotatably about the spindle 15, connected to a toothed belt transmission 24 with the servo motor 2.
  • the toothed belt transmission consists of a pulley 19 which is fixed on a motor shaft 18 of the servomotor 2 and a pulley 21 which is fixed on the nut 5 formed as a ball nut 16.
  • belt 20 connects the pulleys 19, 21.
  • the servomotor 2 radially move to a longitudinal axis 22 of the axially displaceable component 3 and in fix his position.
  • the ball nut 16 is axially and radially via an inner ring 9 and outer ring 10 of a radial bearing 6, which is formed as a deep groove ball bearing in the embodiment shown and axially between two stops 25 in one Housing cover 26 of the steering gear housing 17 is fixed positively mounted.
  • tie rod forces are in operation of the power steering 1, which are dependent on the deflection and other geometric and dynamic driving influences and forces on steered wheels of the motor vehicle, applied bending moments and shear forces.
  • the radial bearing 6 with a bearing ring 7, such as an outer ring 10 of the radial bearing 6 via an annular element 8 supported with elastomeric properties of the annular stops 25.
  • the elements 8 with elastomeric properties are in the embodiment shown on metal discs 11 vulcanized rubber rings with a greater material thickness in the region of the outer ring 10 of the radial bearing 6 than in the rolling elements of the radial bearing 6.
  • the metal discs 11 are on the circumference of the ball nut 16 and leave simply by pushing on its peripheral surface mount.
  • a pivoting mobility of the spindle 15 can be made possible by a suitable geometric design of the radial bearing 6 surrounding components or by the components of the radial bearing 6 itself.
  • the outer ring 10 of the radial bearing 6 has at its outer periphery 13 a reaching around its circumference convex curvature 12, which allows pivotal movement of the spindle 15.
  • a further embodiment is shown greatly enlarged in a longitudinal section of a power steering system according to the invention.
